In the Hindu scriptures Kali Yuga (the age of the demon) is one of the four stages the world goes through. It is a nonspiritual age of ignorance, sin and short life span.
Hindus believe that human civilization degenerates spiritually during the Kali Yuga. In it people are as far away as possible from God. Hinduism often symbolically represents morality as a bull. In the first stage of development, the bull has four legs, but in each age morality is reduced by one quarter. By the age of Kali, morality is reduced, so that the bull has only one leg.

We currently have dead sure answers on what life is and what death means. All other ideas are considered as ignorance.
Death is a journey that everyone makes. We are doing it on our own and nobody knows where it takes us. The question of what death means is exactly the same as what life means. We sometimes consider the question about death as trivial or uninteresting. By that we also handle the question of what life means in the same way.
